My 1987 F150 4x4 5.0 was starting and running OK. It is not driven often so sometimes it is a week or two between uses. Tried to start it last week and it would crank but would not start. Been throwing parts at it new parts so far are coil, distributor cap and rotor, ICM, condenser. Still no spark. What is my next move.

There were a lot of ants in the engine compartment is there some part they could have gotten into that would cause this no spark condition?

I live in a rural area and the owner of the only local shop passed away. Nearest shop is 20 miles away. I hired a guy who calls himself a mobile mechanic and he replaced the ICM and condenser. Also the inline fuel pump which is when I decided I had had enough as I doubt he ever tested for it prior to replacing the pump. I sprayed some starter fluid in the throttle body and got no response. Also bought a spark tester and tested after changing the distributor cap and coil.

Since I have replaced the coil, condenser, rotor, distributor cap, ignition control module, what's left? Pick up coil and distributor? Anything else that would be likely to cause a no spark issue? I would very much appreciate some advise.

Have u checked your fuses..My 96 just died going down the road one day would turn over and not crank..Turned out the o2 sensor plug got against exhaust melted and was shorting out blowing the ecm fuse..

Check the fusible link for the computer.

Recapping, the truck has been down for a while. No spark. I tried throwing parts at it without any luck. Rural area with no mechanics. Repair shop just opened up so I had the truck towed there to see what they could find. They replaced the computer and now have fire into the distributor but not out of the module. They tried several modules without luck. The guy says he is stumped. Any ideas? Throw them at me and I will pass them along. Thanks for your help. I don't want to give up on it as the body is in great shape and the engine has less than 100K on it.

PIP.

Chris_1 I am sorry but I don't know what PIP means.

PIP sensor or pickup coil is inside the distributor

thanks for the suggestion. Drove by the shop and I was mistaken, he had said the was power into the ignition control module but not out of it to the distributor. Tried several ICM with no luck. He had already checked the PIP. Odd thing is he now has another 87 same model truck, with the same problem in his shop. Said that he has queried all his mechanic friends and searched online but nothing has worked yet.
